Pentium D 940 Heatsink issues

[jplanet]

I've just installed a Pentium D 940 onto an Intel 945PSN. I had some trouble getting the heatsink assembly to push in to the mobo, and the first time I tried to POST it shut down with a thermal warning. So, I replaced the factory pad with some Arctic Silver...when I did this, I noticed that one of the plastic feet on the heatsink assembly was a little bent, and put up quite a fight getting back into the board.

Now I can POST, the CPU temp goes from about 56C to 62C after about 15 minutes of being on. That seems a bit warm, the chassis temp is about 30C.

Is it wise to leave it like this, or should I perhaps change the heatsink assembly for a new one?

I wouldnt be comfortable with 62c for a idle temp if it is idle.

If its load its fine.

Well, it seems that I must have compromised the ability of the assembly to effectively snap into place, one of the pegs just refuses to push through the board the way it's supposed to...After a third attempt at reinstalling it, cleaning everything and replacing the Arctic Silver, it still shoots up to 62C just after a few minutes in cmos.

Just ordered a replacement, wish me better luck on that one!

Intel sells replacement pin kits for 2 bucks and thermal pads for a buck.

If the replacement you ordered isn't the Intel unit, it will void your CPU warranty.

With the 775 pin heatsinks start on one corner and get it locked in then go to the opposite corner, then the others one at a time.

Thanks for the head's up, I did order an Intel replacement. Out of all of the tasks in my first build, I thought that this was the most awkward -- it just doesn't feel right having to push so hard into the board. I'll know better next time!

It's easier to install the LGA775 heatsink with the motherboard out of the case. Follow the instructions found here.

i had a similar exp with the intel heatsink i received it and two of the pins were bent i used a pair of pliars to bend them back and they went in fine....too bad the board was shot though

Cricket, that link is brilliant! Thanks!

Now, why doesn't Intel just print that out and stick it in the box?!

Agreed... While installing my first 775 HSF, I was squinting quite hard at the little diagram that Intel had supplied.

Lowers costs, I guess.
